Method Detail

• getComparator

  public KeyValue.KVComparator getComparator()

• getStoreFileScanner

  public StoreFileScanner getStoreFileScanner(boolean cacheBlocks,
                                     boolean pread)

  Get a scanner to scan over this StoreFile. Do not use this overload if using this scanner for compactions.

  Parameters:

  cacheBlocks - should this scanner cache blocks?

  pread - use pread (for highly concurrent small readers)

  Returns:

  a scanner

• getStoreFileScanner

  public StoreFileScanner getStoreFileScanner(boolean cacheBlocks,
                                     boolean pread,
                                     boolean isCompaction,
                                     long readPt)

  Get a scanner to scan over this StoreFile.

  Parameters:

  cacheBlocks - should this scanner cache blocks?

  pread - use pread (for highly concurrent small readers)

  isCompaction - is scanner being used for compaction?

  Returns:

  a scanner

• getScanner

  @Deprecated
  public HFileScanner getScanner(boolean cacheBlocks,
                                   boolean pread)

  Deprecated. 
  Warning: Do not write further code which depends on this call. Instead use getStoreFileScanner() which uses the StoreFileScanner class/interface which is the preferred way to scan a store with higher level concepts.

  Parameters:

  cacheBlocks - should we cache the blocks?

  pread - use pread (for concurrent small readers)

  Returns:

  the underlying HFileScanner

• getScanner

  @Deprecated

  Parameters:

  cacheBlocks - should we cache the blocks?

  isCompaction - is scanner being used for compaction?

  Returns:

  the underlying HFileScanner
